CHECK-ROWZCORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 410,140, dated September 3,

Application filed March 18, 1889.

To all whom it may concern.-

Beit known that I, GEORGE L. BANKS, a citi-- zen -01 the United States, residing at Fall River, in the county of Greenwood and State of Kansas, have invented new and useful Im provements in Check-Row Corn-Planters, of

, which. the following is a specification.

My invention relates to improvements in check-row corn-planters; and it consists in certain novel features hereinafter'described and claimed.

In the accompanying drawings, Figure lis a perspective view of a planter provided with my improvements. Fig. 2 is a vertical section. Fig. 3 is a similar view showing the parts in a different position. Fig. 4 is a detail perspective view of the pitman and the pawl and valve connected thereto; and Fig. 5 is a detail perspective view of the seed-disk, looking at the under side of the same.

The corn-planter constructed in accordance with my invention is provided with a transverse beam A, the seed boxes or hoppers B, erected thereon near the ends of the same, and the runners 0, all of the usual construction.

wire passes.

On the front side of the transverse beam A, near the ends of the same, I provide the bearings D, in which the rock-shaft E is journaled,

the said rock-shaft being provided at its ends with the upwardly-projecting forked leverarms F, over the ends of which the check-row The rock-shaft is further provided near one end with the radial pin G, which plays between the stops H H on the side of the adjacent bearing D to limit the movement of the rock-shaft. At the center I arrange around the, rockshaft a coiled spring I, one end of which is secured to the under side of the transverse beam A and the other end of which is secured to the rockshaft. This spring serves to return the rockshaft to its normal position after it has been operated by the check-row wire.

The runners C are provided in their rear portions with the passages J, through which the seed is discharged, and in the said pas- Serial No. 303,714. (ITo'model-l to said crank-arms and their rear ends connected to the upper ends of the valves by the lateral arms N, as shown. Each of the pitmen M carries a pawl O, which extends upward through a longitudinal slot P in the beam A and engages the ratchet-teeth Q, formed on the under side of the seed-disk R. These pawls are held normally projected up through the said slots by the springs S, secured to the pitmen and bearing against the pawls. The spring I holds the rock-shaft normally in such a position that the crankarms L will be thrown backward and the pit men thereby caused to carry the upper ends of the valves K rearwardly, so that the lower ends of said valves will swing inward and close the passages in the runners to prevent the discharge of seed. As the machine is drawn over the ground, the knobs on the. check-row wire coming in contact with the lever-arms F will throw the said lever-arms backward, so as to rotate the rock-shaft and thereby draw the pitmen forward and move the valves so as to open the passages in the runners. The forward movementof the pitmen also causes the pawls earriedthereby to engage the ratchet-teeth on the under sidesof the seed-disks to force the said disks forward, so as to bring another supply of seed over the seed-opening in the beam A, through which it will fall into the passages in the runners and escape through the same to the. ground. WVhen the knob on the cheek-row wire has escaped from the lever-arm, the spring I at once returns the rock-shaft to its normal position, as will be readily understood.

It will be observed from the foregoing description that I have provided an extremely simple planterin which the seed will be effectually planted in rows and at regular distances apart, and undue escape and consequent loss of the seed will be effectually prevented.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is'

1. The combination, with the beam A, having the slots P, of the vibratory rock-shaft E,

ings and having a radial pin playing between the said stops, the valves mounted in the run- 15 ners, the pitmen connecting the valves with the rock-shaft, and mechanism for operating said shaft, as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in 20 presence of two witnesses.

GEORGE L. BANKS.
